The burner is arranged at the top of the steam generator, generates heat by burning fuel gas, and the burned flue gas is discharged to the atmosphere or recycled from a flue gas outlet 13 arranged at the lower water inlet section 1; the inlet water enters from the bottom of the steam generator and forms convection with the flame direction of the burner so as to achieve the highest heat exchange efficiency
As shown in fig. 2, the casing of the steam guide section 3 is provided with a furnace temperature interface 33 and a flame observation window 34, and if a gas engine with self-ignition protection cannot be adopted, the casing can also be provided with an ignition electrode and a flame/furnace temperature protection interface.

As shown in fig. 3, the casing of the steam section 1 is provided with a hearth observation window 22, and the casing of the steam section 1 is manufactured separately from the steam pipe 211 and is assembled only when the steam generator is assembled.
As shown in fig. 5, when the steam generator is assembled, the shells of the steam guide section 3, the steam section 2 and the water inlet section 3 are fixedly connected together by bolts from bottom to top, and sealing is ensured to form a combustion chamber shell of the steam generator; the steam guide pipe 31, the steam pipe 211 and the water inlet pipe 11 are in sealing butt joint and fixed in the housing; after the steam guide pipe 31, the steam pipe 211 and the water inlet pipe 11 are in butt joint and meet the sealing requirement, a heat exchange component, namely a furnace tube, of the steam generator is formed.
In order to realize automatic control and regulation, valves such as temperature and pressure parts, a liquid level meter and a one-way valve are all connected with a control system.
As shown in fig. 6, the principle of operation of the adjustable modular steam generator of the present invention is as follows:
after the steam generator burner is started, water in the furnace tube is evaporated into steam after absorbing heat of combustion of the burner by water in the water inlet pipe. The water inflow and the power of the burner are controlled, so that the water inflow can be evaporated into steam in the steam generator, and the water cannot be directly discharged to the steam outlet. When the burner is matched with the inlet water, the upper part of the furnace tube is steam, and the lower part is liquid water.
The back pressure valve 63 on the steam conduit 6, the pressure water inlet pipe 11 and the water in the furnace tube are evaporated and expanded, and meanwhile, the burner is matched with the water inlet, so that the water in the furnace tube can be evaporated into steam with certain pressure to be discharged, and the needed steam is provided for the outside.
Because the inflow water and the furnace flame are in convection, the gaseous water generated by combustion in the furnace flame can condense into liquid water condensate on the outer wall of the furnace tube along with the furnace tube with lower contact temperature of the flue gas descending, the condensate drops to the bottom of the steam generator due to gravity, and when the evacuation valve 123 is not opened, the condensate can be accumulated in the space of the combustion chamber between the bottoms of the steam generator, and the height can reach the highest position of the inverted U-shaped overflow pipe 121.
When the steam generator is in normal operation, the height of the inverted U-shaped overflow pipe 121 is higher than that of the water inlet pipe 11, the water inlet pipe 11 is fully soaked in condensed water, the temperature of the condensed water is the boiling point temperature of water just condensed into water, and the condensed water is far higher than that of water inlet, and can be preheated by the pipeline of the water inlet section, so that the section of furnace pipe is called a preheating section. The preheating section can obviously reduce the discharge temperature of the flue gas and recover the latent heat of the gaseous water in the flue gas, so that the heat efficiency of the steam generator is obviously higher than that of a common gas boiler.
When the steam generator is in normal operation, water in the furnace tube evaporates in the evaporation section to form an evaporated water-steam interface. A steam pipe 211 between the evaporation interface and the preheating section is called a boiling section; the furnace tubes between the water-steam interface and the steam outlet interface of the steam generator, namely the part of the steam tube 211 and the steam guide tube 31, are called a superheating section. The main process in the boiling section is the liquid water heated gasification (boiling), and the main process in the superheating section is the complete gasification of liquid drops in steam, and the heated temperature of the steam is increased, namely the heat is increased.
When the power of the burner is fixed and the pressure of the steam at the outlet is unchanged, the water inflow is increased, the evaporation interface moves upwards, the heating area of the boiling section is increased, the heating area of the superheating section is reduced, the steam yield is reduced, and the superheat degree is reduced; conversely, when the water inflow is reduced, the evaporation interface moves downwards, the heating area of the boiling section is reduced, the heating area of the superheating section is increased, the steam yield is increased, and the superheat degree is increased.
When the power of the burner is certain and the pressure of the steam outlet is unchanged, the evaporation interface is adjusted and changed, so that the proportion of the heated areas of the superheating section and the evaporation section is actually changed, the evaporation interface is reduced, the superheat degree of the steam can be increased, and the steam yield is slightly reduced; raising the interface of the steam generator, increasing the steam yield, and reducing the superheat degree of the steam until the superheat degree is reduced to 0 ℃, namely producing saturated steam.
Usually, after the user determines, the requirements of steam pressure and temperature are also fixed, and the steam consumption can fluctuate; while the pressure and temperature of the steam required are different for different users. According to the needs of different clients, on one hand, a proper number of evaporation units 21 are selected to obtain different heating areas of boiling sections and heating areas of superheating sections; on the other hand, the water inflow is controlled by the liquid level meter, and the proportion of the boiling section and the superheating section is regulated, so that different steam quantities are realized.
In order to obtain a wider range of steam quantities, the present invention provides a steam generating device comprising several steam generators arranged in parallel, i.e. several independent steam generators are combined, as shown in fig. 7.
The burner of each independent steam generator is connected with a main fuel supply pipeline 82, a water inlet pipe is connected with a main water supply pipeline 81, a steam conduit is connected with a main steam collecting pipeline 86, a flue gas outlet is connected with a main smoke discharging pipeline 85, and an inverted U-shaped overflow pipe is connected with a main water discharging pipeline 84.
